lilo it known 'that l, links 'Piani-mslm MIT- r, oi' ffizilesund, in the llingdoin of Nory, have invented certainnnew and useful improvements in. the Apparatus tor Hard 'I "wisting of Fine and 'llhick y'l`hrcadsg and l do hereby declare the following to be a full, clear, and exact description ofthe invention, such ss will enable others skilled in 'the art to which it appertains to 4make and the saine, reference being` had to the acpanying drawings, and 'to letters or iigreierence .marked thereon, which it oit this specification.

it has not been possible te pro with s suiiicient twist by is :the ordinary twisting` inachines ri spindles er fliers, because these machines have not the required dispositions i'or stretching and guiding the thread, so that only s limited degree oi" twist can he obtained. But this 'twist is not suiiicient for r tin e ha 'twisten the thread regulated hoth twistin s.v

invention has .tor its object sn appsM i herd-twisting of the thread, 'to he i on an; erdii'iery twisting machine or e. siinilar machine, by means the thread is given a sutiicient lioretwist and head twist) and from the thread is passed directly to the enig machine in a continuous process.

By means of this apparatus the twist can regulated and he `sgot as hard l(Without bsd twist) end perfect as it is required for t' e purpose, which it has to fulfil. The Yisting; can he dene to the right or to theA the drawing a constructional forni of y twisting apparat-iis according to the inon en is shown.

pulley 0. n the free ends of the screw spindles, tulf'isting 'trames l0, ll and l2 are fastened, the end pieces of which may preterably consist ol disks le, l5 and 16, which are fastened to the screws. On the tree side of the said disk pulleys 18 and 19 for the thread 20 coming' from the thread reels 2l are journaled. Un the disks is further fastened i pipe 24, the free end of which is connected ,with and led through a ringr 25, which surrounds the thread`reel. This ring,` is connected to the disks by means of rods 2S. The pipe mentioned above serves to lead the thread troni the thread reels and may be furnished With a lateral cutting in order 'to facilitate the thread to enter the pipe. From `the pipe the thread is led on to the pulley l@ and from this over the pulley i9 and further through a bore 29 mede in the screw spindle, in which the twisting takes place, and further over the feeding disks and 3l, which are fastened on shsits and 3% connected with each other by means oi' wheels 35 and 36 and are driyeirifrom the pulley 38 by a belt, seid belt coiningfrnni the twisting machine. The thread is now led on 'to the twisting machine with fliers, Where the heed twist is carried out.

The spindles .4:0 of the thread reels which are enteredinto the axial bore 29 inthe screw spindles are on their inner end furnished with a nose 43, which projects into a slot made in the disks 14, l5, 1G and is furnished with a groove le in order to permit the thread to pass. The outer end of the spindles are journaled in the bearings 45, i6 and 47 in a manner, 'which facilitates the disei'igaging. rl`he bearings are fastened to brackets mounted on the upstanding end piece 18. These bearings consist of a xed base member 50, and a movable ripper part .5l which een he turned about the pivot 52 and kept in its normal position by a spring 53. @n 'the outerpart the xed as Well as the rotatable part of the hearing'is sloped toward Jdie shaft in order to facilitate the entering ci the latter.
